i think some player's problem are not skills but mental...playing under big pressure is a good sign of leadership..
in Turkey..Neslihan ,Gözde and Eda are these kind of players . they like pressure
Lonneke's problem could be mental..same for Alesia Rhyliuk..they are both skilful players
That's a bad news for Lönneke. One can improve skills by practice while mental is kind of natural thing and hard to change, especially at her age in volleyball career.
As what I've observed during recent two seasons, Guidetti has some character that he can turn a simple win into complicated lose.
